Application July 8, 1935, Serial No. tilt 03 2 Claims.

The invention relates to an air conditioning machine and more especially to a portable air condltioner.

The primary object of the invention is the provision of a machine of this character, wherein dust laden air can be treated so that when such air passes through the machine it will be clarified and conditioned, the machine serving as a humidifier with a reduction in the temperature of the air in addition to the circulation and. washing of the same.

Another object of the invention is the provision of a machine of this character, wherein the same is readily portable so that it can be placed at the localities required within a house or other enclosure, performing the services of a fan, hu-

midifler, air Washer, air circulator and thoroughly cooling and cleaning the air so as to give more comfort within the building or other enclosure.

A further object of the invention is the provision of a machine of this character, which is comparatively simple in construction, thoroughly reliable and eihcient in its operation, convenient for good service, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a front elevation of a machine constructed in accordance with the invention.

Figure 2 is a vertical longitudinal sectional View thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Similar reference characters -indicate corre sponding parts throughout the several views in the drawing. 7

Referring to the drawing in detail, the machine comprises a casing 5 preferably made from sheet metal and is of substantially rectangular shape having at its bottom the supporting legs 6 to rest upon a foundation, floor or the like so that the bottom I of this casing is elevated slightly with respect to the foundation or floor line while (El. Mil-92) horizontal shaft i2 which is midway of the said casing and parallel with the longitudinal extent thereof. This shaft carries spaced disks i3 constituting rotors which operate in liquid it such as water contained within a pan forming a 5 container for the liquid. This pan it rests upon the bottom '5 interiorly of the casing 5.

Arranged interiorly of the casing 5 and extending upwardly is an air direction hood i6 extending about one side of a bladed fan wheel i'i constituting a blowerfor air circulation and the axle it of this wheel is journaled in the upper cross supports it. The hood it has ends i9, these being perpendicular and spaced from opposite ends of the casing 5, the disks constituting the rotors it being in their spaced relation to each other within the lower portion of the hood.

At one side of the hood i6 between one end. of the casing 5 and an end adjacent thereto of the hood is a support 20 for an electric motor 2i, it adapted to be in circuit with a current supply and the shaft 22 of this motor carries a belt wheel 23 having trained thereover an endless belt 2% which is also trained over a belt wheel 25 fixed to the shaft it so that the motor 2i is a power source for the blower. The shaft it also is fitted with a belt wheel 26 having trained thereover an endless belt 2'! which is also trained over a belt wheel 28 fixed to the shaft i2 so that motion from the shaft it is transferred to the shaft i2 whereby U the shafts i2 and iii will be driven in unison with each other from. the motor 20 when operated. The circuit to the motor 2! has'included therein a hand switch 29 for the opening and closing of the circuit as is common. 35

Formed in the back of the casing 5 at the lower portion thereof is a reticulated or wire mesh panel 30 constituting an air inlet while at the front of the said casing at the upper portion thereof in confronting relation to the blower ill is a retlcum lated or wire mesh panel at constituting an air outlet. The hood H5 at the portion confronting the panel 30 is provided with a window or opening 32 so that air entering the casing 5 can pass therethrough to be drawn upwardly and circulated by the blower I! for discharge through the outlet or the panel 3! from the machine.

Within the hood is above the disks or rotors I3 is a horizontally disposed screen 33 made from. wire mesh fabric while at the rear of the disks 50 or rotors i3 and rising from the bottom of the pan I5 is a rearwardly inclined splash shield or plate 34 so that the water collected by the disks or rotors it when delivered therefrom by centriiugal force will be brolren up by contact with 55 the shield or plate 34 to effect a mist for the washing of the incoming air through the panel 36 during circulation thereof under the action of the blower IT.

The motor 2i is adjustably connected with the support 20 so that its position can be changed and thus the belt 24 slackened or tightened as the occasion may require.

The hood l6 at its lower portion constitutes a mist chamber and at this point the air is humidifled and the water vaporized. This process of vaporization changes the sensible heat into latent heat whereby the changing of sensible heat into latent heat of vaporization reduces the temperature of the air treated within the machine.

The pan I5 is filled with water in any desirable manner preferably through the open top of the casing 5 when the lid or cover 8 is raised.

The circuit wiring to the motor 2! includes a connecting cable 35 having a separable terminal plug 36 of conventional kind for tapping into a house current system.

The spaces between the ends of the hood i6 and the ends of the casing 5 accommodate the belt wheels, belts and motor hereinbefore described.

In the working of the machine the air entering the same will be conditioned and humidified prior to its discharge from the machine. In other words, the machine serves as a fan, humidifier, air washer or air circulator and a medium for cooling and cleaning the air.

The fan wheel operates within a casing S! having the end openings 38 concentrically about the axle I8 for central sucking action in the operation of the fan and between the screen 33 and the lowermost portion of the casing 31 is a series of spaced zigzag form baffles t9, these being extended crosswise of the hood 58 so as to function as eliminators whereby the air in passing between them will be caused to change direction of flow of such air and the holding back or dropping of particles of sand, dust, etc., from the air in its flow to the fan. These baflies 39 are in the form of metal strips and are uniformly spaced from each other in the mounting thereof so that the air flow in passing upwardly between aosaass the strips is changed in direction sharply. This change in direction prevents direct splash of water reaching the blower and also causes the air when changing direction to drop particles of dust, pollen, etc.

What is claimed is:

1. A machine of the character described comprising a portable casing having substantially fiat sides and ends, the sides being formed with air intake and air outlet openings, respectively, and arranged in different planes from each other, a hood within the casing and having an opening confronting the inlet opening, a blower housing at the upper end of the hood and having a lead to the outlet opening and also side communication with the hood, a horizontally journaled blower fan within said housing, a water pan within the casing at the bottom thereof, a plurality of disk-like rotors operating within the pan, a splash shield located between said rotors and the inlet opening, a screen within the hood between the blower housing and said rotors, driven connections between the pan and said rotors, and power means within the casing and operating said fan.
